Hi everyone,
On my site there are quite a few files up to download. They are linked at the bottom of posts through the default file upload/attachment feature. Download method is private, and users must be logged in to download files.

Here is what happens. When someone goes to click to download, I get in the logs an entry for successful download, followed by multiple entries for 'page not found', under 'anonymous' instead of the user's name (but from same IP), that queries any of the following:
/node/3 (my front page)
system/files/[type]/[year]/[month]/ (the 'virtual' root of the folder where the file is located, as defined in upload_path module).
On the user side, the download happens seemingly normally.

I tried with Firefox and got two extra "/node/3" requests. I tried with IE8 and got 4 "node/3" requests, 1 request to the root, and 1 request to download the file as anonymous user, with the associated deny action.

Past users have also had requests to _vti_bin/shtml.exe/_vti_rpc and _vti_inf.html

Why would I care if it works? For one, I don't know if it is a sign of a deeper problem. Second, I am sharing the Drupal logs with my superiors and they would probably not understand if these are flukes and might get worried about the quality/stability of the site.

Related modules I am using are upload path and download_count.

I also have a bit of .htaccess wizardry to force the file download dialog to pop up instead of opening the file in the browser.

#Force file download for the following:

<FilesMatch "\.(pdf|PDF|doc|docx|ppt)$">
		ForceType application/octet-stream
	Header set Content-Disposition attachment
</FilesMatch>

Could any of these cause the problems? Why would there be all of these requests?
Thanks
